Calculates the Volume and 3D Area of a TIN above and below a horizontal reference plane defined by the user specified level. The function analyzes the location of each triangle relatively to the reference plane and calculates its volume and area below and above the plane. The result is the accumulated values for the below and above portions of the triangles stored in a new or existing text file.

Parameters
| Expression | Explanation |
|---|---|
| Function Name | TinVolume |
| <input tin> | A String representing the input TIN dataset. |
| <output file> | A String - the full name of the output text file (new or existing). |
| <level> | A Double indicating the level of the reference plane for which the volume calculation will be performed. |
ETGWPath used in the table below is the full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETSurface\ETSRun.exe")
| Language | Syntax |
|---|---|
| Python | subprocess.call([ETSPath, "TinVolume", "input tin", "output file", "level"]) |
| .NET using ETSRun.exe | StartInfo.FileName = ETSPath StartInfo.Arguments = "TinVolume" "input tin" "output file" "level" |
| .NET using ETSOutX.dll | TinVolume(input tin, output file, level) |
| ArcPy | arcpy.TinVolume("input tin", "output file", "level") |
Notes:
<> - required parameter
{} - optional parameter
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
